Product details
Overview
MRF300ANBN-150M from NXP Semiconductors is a high-ruggedness, 300 W CW, 50 V LDMOS RF power transistor optimized for HF/VHF broadband amplification up to 250 MHz. It delivers 330 W peak output at 230 MHz (100 µs pulse, 20% duty), 79.7% drain efficiency at 13.56 MHz, and operates with 50 V DC supply and 100 mA quiescent drain current - deployed in industrial plasma etching and MRI RF power stages.
For engineers reviewing the MRF300ANBN-150M datasheet, MRF300ANBN-150M pinout, MRF300ANBN-150M application, or MRF300ANBN-150M equivalent, this page provides verified electrical specs, ruggedness validation at >65:1 VSWR, thermal impedance data (0.13 °C/W pulsed), TO-247-3L package mapping, and direct alternative part guidance for HF/VHF RF amplifier design.
Technical Context
This device is an enhancement-mode lateral MOSFET with integrated ESD protection (HBM Class 2, CDM Class C3), rated for –6.0 to +10 V gate-source voltage and –0.5 to +133 V drain-source voltage. Its mirror-pinout variant (MRF300BN) enables push-pull two-up configurations without layout redesign.
Characterized across 13.56–230 MHz reference circuits, it maintains ≥73% drain efficiency and ≥23 dB power gain in CW operation, with proven load mismatch tolerance (>65:1 VSWR at 40.68/230 MHz under 3 dB overdrive) and junction temperature range of –40 to +175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MRF300BN | Mirror pinout (Pin 1: Drain, Pin 2: Source, Pin 3: Gate) - identical electrical specs and thermal performance | Required for push-pull layouts where gate drive symmetry demands reversed terminal assignment | Select MRF300BN only when implementing complementary-device configurations; otherwise MRF300ANBN-150M (A-pinout) is standard. |
| MRFE6VP6300H | Higher Pout (300 W CW @ 225 MHz), wider bandwidth (1.8–250 MHz), but lower efficiency (72% @ 225 MHz) and no documented >65:1 VSWR validation | Better suited for wideband multi-band base stations; less ideal for fixed-frequency high-ruggedness ISM applications | Choose MRFE6VP6300H only when bandwidth flexibility outweighs ruggedness and efficiency requirements - not drop-in compatible. |

FAQ
What is the maximum continuous drain current rating for MRF300ANBN-150M?
The MRF300ANBN-150M does not specify a maximum continuous drain current in its datasheet. Instead, it defines safe operating limits via total device dissipation (272 W @ TC = 25 °C), junction temperature (–40 to +175 °C), and thermal resistance (0.55 °C/W CW). Actual current depends on bias point, frequency, and heatsinking - typical IDQ is 100 mA in reference circuits.
Does MRF300ANBN-150M support Class C operation, and what enables it?
Yes, MRF300ANBN-150M supports Class C operation due to its extended negative gate-source voltage range (–6.0 V) and integrated ESD protection, which improve gate robustness during hard switching. This capability is explicitly cited in the "Features" section of the official NXP datasheet for MRF300AN/MRF300BN.
Is MRF300ANBN-150M pin-compatible with MRF300BN?
No - MRF300ANBN-150M uses the MRF300AN pinout (Pin 1: Gate, Pin 2: Source, Pin 3: Drain), while MRF300BN has mirrored pinout (Pin 1: Drain, Pin 2: Source, Pin 3: Gate). They are functional equivalents but require separate PCB layouts; neither is pin-to-pin compatible with the other.
What is the recommended gate bias voltage for linear operation of MRF300ANBN-150M?
For linear CW operation, the recommended gate quiescent voltage is 2.5 Vdc (typical) at VDD = 50 Vdc and IDQ = 100 mA, as specified in Table 5 of the NXP datasheet. Gate threshold voltage ranges from 1.7 to 2.7 Vdc, so bias must be set within this window to ensure stable Class AB conduction without cutoff or excessive current.
Can MRF300ANBN-150M be used in pulsed RF applications above 230 MHz?
No - the highest validated pulsed performance is at 230 MHz (330 W peak, 100 µs, 20% duty cycle). While the device is rated for operation up to 250 MHz, no pulsed characterization data exists beyond 230 MHz in the official NXP datasheet; use above that frequency should be limited to CW or verified by customer testing.
